Answer 1

n = int(input())
L1 = []
L2 = []
for _ in range(n):
    L1.append(input())
for _ in range(n):
    L2.append(input())

def merge_list(L1,L2):
    L = []
    for v1,v2 in zip(L1,L2):
        L.append(v1)
        L.append(v2)
    return L

for i in merge_list(L1,L2):
    print(i)

def getScores(n):
    scores = n * [0]
    for i in range (n):
        scores[i] = float(input())
    return scores
def meanScore(scores):
    mean_score = sum(scores)/len(scores)
    return mean_score
n = int(input())
scores = getScores(n)
print("%.2f" % meanScore(scores))
